Figure 6.

Immunofluorescent images of vascular network-like structure formed within PEGylated plasma gels prepared with 12.5 U of thrombin on day 11. Representative images of frozen sections stained (red) for ANGPT 1, NG2, α-SMA, and actin microfilaments (F-actin). Cell nuclei were stained with DAPI (blue). Scale bar within the panel of DAPI, F-actin, α-SMA, and merge = 50 μm; DAPI, NG2, ANGPT1, and merge = 25 μm. DAPI, 4′,6-diamidino-2-phenylindole, dihydrochloride. Color images are available online.
